Public transportation in New Jersey is expected to be packed Wednesday, as a sold-out concert kicks off in Hoboken, and MetLife Stadium in East Rutherford is expected to fill to capacity.

Nearly 100,000 Jewish men and women will attend the Siyum HaShas at MetLife Stadium to celebrate their study of the Talmud. Attendees have spent years studying all 2,711 of the Talmud, Judaism's interpretation of Torah.

New Jersey Transit has issued an alert warning of large crowds at Secaucus Junction, New York Penn Station, Hoboken Terminal and Newark Penn Station beginning around 4 p.m. on Aug. 1. Customers should allow for extra travel time throughout the evening. The program begins at 7:30 p.m.

Officials say there will be a large security presence at MetLife Stadium, and there will be heavily armed state police teams in place as a precaution.

Additionally, a sold-out concert for the band Mumford & Sons in Hoboken has New Jersey Transit preparing extra service. The concert at Pier A Park will close streets in the area, and Warrington Plaza adjacent to Hoboken Terminal will also be closed by NJ Transit.

Additional PATH trains will operate between 9 p.m. and 11 p.m., and NJ Transit will also be providing additional service.
